Remember last year? We hardly do. So much has happened since then, from hurricanes to sharknados to twerkquakes, that we can't recall if 2012 even existed. (Spoiler: It did not.) So, whatever celebrity-inspired, YouTube-featured costume was deemed "hot" that year has been lost to the annals of time, dumped at the very bottom of a Ricky's discounted Halloween bin.
Taking a look at pop culture costumes from last year, two years ago, and even ten years back is a strange, bizarre trip through time. Chilean miners? Ali G? Psy? We're betting that most of these are not going to be reprised any time soon — which makes them all the more fun to reflect upon.
